CURTAIN-FIXTURE.

Specification of Letters Patent No. 31,628, dated March 5, 1861.

To all whom it may concern:

Be it known that I, SILAS S. PUTNAM, of Dorchester, in the county of Norfolk and State of Massachusetts, have invented an Improved Curtain-Fixture, of which the following is a full, clear, and exact description, reference being had to the accompany ing drawings, making part of this specification, in which- Figure l is a view of the curtain and fixture; Fig. 2, a view of one of the brackets detached.

In the curtain fixtures heretofore made, various devices have been employed to hold the curtain at any desired height to which it may be raised, most of these having in View the dispensing with weighted tassels. To accomplish this, friction has been applied to the spool or the rod on which the curtain is rolled by means of springs or weighted levers.

The object of my present invention is to dispense with all such appliances, which add to the cost of the fixture, and to its liability of derangement; and my invention consists in a curtain fixture in which the rolling motion of the journal on which the roll is hung, is used to carry the spool or a ratchet connected therewith into contact with a stop which will hold the curtain in position; while a slight tension applied to the cord which operates the roll is suflicient to keep the spool or its ratchet from contact with the stop when lowering the curtain.

That others skilled in the art may understand and use my invention I will proceed to describe the manner in which I have carried out the same.

In the said drawings A represents the window frame to which are attached the brackets a b. The latter is shown detached in Fig. 2.

The curtain B. is attached to a roll C which carries at one end a spool D. one side of which is notched to form a ratchet wheel 0. The journal or pivot in one end of the roll C. rests in a notch in the bracket a, and the journal 2' at the other end of the roll enters a slot 7. in the bracket 7). This slot or oblong hole allows this end of the roll to move a short distance horizontally.

A pin or stop 6 projects from the inner face of the bracket b. in such a position that it will intercept the path of the teeth of the ratchet wheel c when the journal is at the end of the slot 7 next to the stop, but will be cleared by this ratchet wheel, when the journal is at the opposite end of the slot. A cord E. wound on the spool D serves to raise the curtain B.

The following is the operation of this fixture: As the cord E. is drawn down and unwinds from the spool D. the curtain B is rolled up on the rod (1, the spool turning in the direction of the arrow, the revolutions of the journal 2' in this direction cause it to travel along the bottom side of the slot f, toward the outer end of the slot, and away from the pin 6, this carries the ratchet wheel 0 clear of the pin. But the moment the cord E. is released from the hand of the operator, the curtain by its weight unrolls a short distance, (say one or two inches.) This revolves the roll and its journal i in the opposite direction, the journal rolling along on the bottom of the slot f. toward the pin 6. brings the ratchet wheel 0 into contact with the pin, and stops the further descent of the curtain. \Vhen it is desired to lower the curtain, a slight pull-on the cord E draws the spool and its journal 2' toward the front end of the slot f, when by allowing the cord to slip through the hand while a slight tension is kept on the cord, the curtain may be lowered without allowing the spool to run back toward the pin 6; or the curtain may be drawn down by the cord and tassel F. without drawing it out away from the window. The slot 7''. may in some cases be slightly inclined.

hat I claim as my invention and desire to secure by Letters Patent is A curtain fixture consisting of the bracket Z). with its slot and the roll C. the ournal i of which by rolling along on the bottom edge of the slot, carries the roll or its spool into contact with a stationary stop substantially as set forth.
